[Hepatobiliary gammagraphy in the diagnosis of Dubin-Johnson syndrome in children].

Using hepatobiliary gammagraphy (99mTc-EHIDA), the authors made 26 examinations in six families with Dubin-Johnson's syndrome. From a series of gammagrams they evaluated the hepatobiliary kinetics and from measurements of the activity of series of blood samples they assessed the half-time of decline of the rapid (Tk1) and slow (Tk2) phase of the curve and the percentage of retention in blood during the 45th minute (R45). The values in a group of normal subjects were 3.
